Hi Scott,

I thought we were talking about hardware reliability, not OS.  I remember a
friend 30 years ago designing & building his own CPU (4-bit machine, the
only i/o was LED's and toggle switches) and the chip he was using for a CPU
would overheat and start adding 2 + 2 and getting 5 until he'd squirt some
coolant on it after which it would start working correctly.  He also
mentioned having problems with noise, and considered finding the right place
to put a capacitor to get rid of it an educated guessing game.

One customer of mine with an S/38 had some CPU fans fail, bringing down the
machine.  The interesting thing was the message -- something about "thermal
regulation device"; they were trying to figure out what it meant when the
machine shutdown.
